Evaluation of various rapid chloride tests for assessing urinary NaCl excretion.

Background/aims: The evidence linking NaCl intake to high blood pressure and probably to other diseases has become stronger. Therefore, a population-wide reduction of NaCl intake is generally recommended. Measuring NaCl excretion in urine is the preferred method for estimating dietary NaCl intake.

[Definition of "salt sensitivity"].

To examine how the term "salt sensitivity" has heretofore been defined, two medical data bases, DIMDI and MEDLINE were searched. 32 clinical studies, published between 1978-1992 and using the terms salt-, sodium- or sodium chloride-sensitive or sensitivity were found and analysed. Salt sensitivity was experimentally determined and applied in quite varied ways to normotensive and hypertensive persons.

Effect of amino acid based dialysis solution on peritoneal permeability and prostanoid generation in patients undergoing continuous ambulatory peritoneal dialysis.

The acute effect of amino acid based dialysis solution on peritoneal kinetics of amino acids and plasma proteins in comparison to conventional glucose-based dialysate was studied in 9 patients with end-stage renal failure on continuous ambulatory peritoneal dialysis. Instillation of 2.6% amino acid solution resulted in raised plasma concentrations of all essential amino acids included in the dialysis fluid (p less than 0.
